EDIVARD ALEXANDER MATTHIAS, OF LIVERPOOL, ENGLAND.

CLOSURE DEVICE FOR BOTTLES, JARS, AND SIMILAR VESSELS.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed December 27, 1904- Serial No. 238,415.

To aZZ whom it may concern:

Be it known that I, EDWARD ALEXANDER MATTHIAS, a subject of the King ofGreat Britain, residing at Liverpool, England, have invented certain newand useful Improvements in Closure Devices for Bottles, Jars, andSimilar Vessels, of which the following is a specification, such as willenable those skilled in the art to which it appertains to make and usethe same.

This invention relates to devices for closing bottles, jars, and similarvessels; and the object thereof is to provide an improved device ordevices of this class which aresimple in construction and operation andwhich involve a particular form of neck for the bottle, jar, or similarvessel and detachable parts connected therewith, whereby the saidbottle, jar, or similar vessel may be quickly, easily, and convenientlysealed and unsealed whenever desired.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which- Figure 1 isa side view of the top partof an ordinary jar provided with my improvement Fig. 2, a plan viewthereof, and Fig. 3 a section on the line 3 3 of Fig. 2.

In the drawings forming part of this specification, I have shown at a anordinary glass or similar jar, and this jar is provided with a neck (1the top portion of which is provided with segmental ribs or flanges 1),two of which are shown, and these ribs or flanges b in the form ofconstruction shown extend half-way around the ar, and said ribs orflanges are triangular in cross-section and are much wider at one endthan at the other, the wider end being at the opposite sides of the neckof the ar, as clearly shown at b in Fig. 2, and by reason of this formof construction the narrower end of said ribs or flanges are also at theopposite sides of the neck of the jar. The neck of the jar, at the topthereof, is beveled or downwardly and inwardly inclined both inside andoutside, as shown at c in Fig. 3, and said beveled or inclined portionis formed partially in the ribs or flanges b and in the neck a and atthe bottom of the incline on the inner side of the neck is an annularshoulder d, on which in practice is placed a packing-ring e of anysuitable material. I

also provide a cap j; the perimeter of which is beveled or inclined, asshown at f to correspond with the bevel or inclination at c in the topof the neck a and said cap is also provided with a depending flange orrim f 3 of such diameter as to fit within the neck a and between theflange or rim f 3 and the beveled or inclined portion f 2 of the cap fisan annular groove or recess f, in which the packing-ring 6 also fits.The smaller ends of the ribs or flanges b, in addition to being of lesstransverse Width than the wider ends thereof, are also of less verticaldepth, as clearly shown in Fig. 1, and I also provide an oblong lookingplate or strip 9, the length of which is somewhat greater than thegreatest diameter of the neck a of the ar measured across the ribs orflanges b, and said plate or strip is provided at each end withdownwardly and inwardly directed tongues or projections g and adjacentto each end with similar tongues or projections 9 the latter in the formof construction shown being cut from the material of the plate or stripand bent inwardly and downwardly, and said plate or strip is providedcentrally with a pivotal opening through which passes a pivot-point orprojections f formed on or connected with the Pf- In sealing the jar thepacking-ring e is first placed in position, the plate or strip 9 is thenslipped onto the cap f, the edges of said cap fitting between thetongues or projections 9 and the cap is then placed in position on thejar. In this operation the cap is so held that the tongues orprojections g pass downwardly over the narrow ends of the flanges b, andthe strip or plate 9 is then turned in the direction of the arrow x inFig. 2. In this operation the tongues or projections move between thecap and the corresponding top portion of the neck of the jar, betweenwhich is a narrow annular space when the cap is in position, and thetongues or projections g overlap the edges of the ribs or flanges b, andthe turning of the strip or plate 9 to the right or in the direction ofthe arrow x, as above described, securely locks the cap f in positionand presses it downwardly onto the packingring or gasket 6 and forms aperfectly tight closure device for the ar. The thickness of the tonguesor projections g is less than the space between the cap f and the ribsor flanges b, and this enables the cap fto be forced firmly on thepacking e, and said cap is secured to the locking plate or strip 9 bythe tongues or projections g My invention is not limited to the numberof the ribs or fianges b nor to the eXact position thereof on the jar,and various vessels of this class may be provided withclosure devices ofthis class regardless of the shape of the vessels or the neck thereof.

Having fully described my invention,what I claim as new, and desire tosecure by Let-V ters Patent, is- Y A jar or similar vessel provided witha neck the top portion of which is inclined outwardly both inside andoutside and provided at the bottom of the incline on the inner side withan annular shoulder and at the top of the incline on the outer side withsegmental flanges or ribs on the opposite sides of the neck, thetransverse Width of which increases from one end thereof to the otherand in opposite directions; and closure devices consisting of apacking-ring placed on said annular shoulder, a cap the perimeter ofwhich is inclined inwardly and downwardly and provided at the bottom ofthe inclination with an annular recess adapted to receive saidpacking-ring, the diameter of the cap at the top and of theinwardly-inclined portion of the neck being such as to form a narrowannular space between the said cap and neck when the cap is in position,and a locking plate or strip placed transversely of the cap and adaptedto turn thereon, said plate or strip being provided at its opposite endswith inwardly and downwardly directed tongues or projections adapted toengage the flanges or ribs at the top of the neck, and adjacent to theends with downwardly and inwardly di-" rected tongues or projectionsadapted to engage the edges of the cap and 'to enter the annular spacebetween the cap and the top portion of the neck, substantially as shownand described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing witnesses, this 10th day ofDecember, 1904.

- EDWARD ALEXANDER MATTHIAS.
